Nemotron 3 Ultra 的混合 SSM+MoE 架构解决了长序列推理的高成本痛点，做长上下文应用或工具调用的开发者值得关注，可以直接期待其发布。
Nvidia 将在几天内发布 Nemotron 3 Ultra 模型。该模型采用混合状态空间模型（SSM）与混合专家（MoE）架构，SSM 部分专为长序列设计，使模型能够更长时间地保持推理或使用工具，而不会被常规注意力机制的计算成本压垮。黄仁勋在 NVIDIA GTC Taipei 2026 上宣布了此消息。

Nemotron 3 Ultra will be available from Nvidia in few days.
Hybrid SSM (state-space models) + mixture-of-experts architecture.
The SSM part is built for long sequences, so the model can keep reasoning or using tools for longer without getting crushed by the usual attention cost.
